WDG-4G
The Indian locomotive class WDG-4G (GE ES43ACmi) is a class of dual-cabin freight-hauling diesel-electric locomotive used by the Indian Railways (IR). The locomotive is designed by GE Transportation and is based on its Evolution Series, which are used in North America. The class is meant for freight hauling and replaces the older American Locomotive Company (ALCO)-designed locomotives, which have been the mainstay diesels of Indian Railways since 1962. Equipped with a 12-cylinder fully turbocharged GEVO engine, it is claimed to be 50% more environmentally friendly than its predecessors and is the first in the country to be compliant with level one of the emission norms set by the International Union of Railways (UIC-1). The locomotive has two cabs for easy reversal, both of which are air conditioned. The locomotive is part of a 13-year contract between Indian Railways and GE Transportation under which 700 such locomotives will be produced indigenously. Diesel Locomotive Facto ...

GE Evolution Series
The Evolution Series is a line of diesel locomotives built by GE Transportation Systems (now owned by Wabtec), initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine. The Evolution Series was named as one of the "10 Locomotives That Changed Railroading" by ''Trains Magazine'' and was the only locomotive introduced after 1972 to be included in that list. The Evolution Series locomotives are some of the best-selling and most successful freight locomotives in United States history. Models Currently, six different Evolution Series models have been produced for the North American market. They are all six axle locomotives and have the wheel arrangement C-C ( AAR classification) or Co′Co′ (UIC classification), except for ...

International Union Of Railways
The International Union of Railways (UIC, french: Union internationale des wikt:chemin de fer, chemins de fer) is an international rail transport industry body. History The railways of Europe originated as many separate concerns, and there were many border changes after World War I and the Treaty of Versailles. Colonial railways were the responsibility of the mother country. Into this environment the UIC was created on 17 October 1922, with the aim of standardising industry practices. Ticket revenue sharing was originally undertaken with the UIC Franc currency equivalent. UIC classification and UIC Country Codes allowed precise determination of rolling stock capabilities and ownership, with wagons assigned unique UIC wagon numbers. The 1990s GSM-R radio telecommunication system is an international interoperability specification covering voice and signalling systems for railway communications whose specification is maintained by the International Union of Railways project Euro ...

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller locomotive manufacturers and Schenectady Locomotive Works, Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks-Morse, Fairbanks Morse Engine for their FM, ALCO line.

Turbo-diesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. * ...

Fault Detection And Isolation
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis of the discrepancy between the sensor readings and expected values, derived from some model. In the latter case, it is typical that a fault is said to be detected if the discrepancy or ''residual'' goes above a certain threshold. It is then the task of fault isolation to categorize the type of fault and its location in the machinery. Fault detection and isolation (FDI) techniques can be broadly classified into two categories. These include model-based FDI and signal processing based FDI. Model-based FDI In model-based FDI techniques some model of the system is used to decide about the occurrence of fault. The system model may be ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Make In India
Make in India is an initiative by the Government of India to create and encourage companies to develop, manufacture and assemble products made in India and incentivize dedicated investments into manufacturing.

Positive Train Control
Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving safely and to stop them when they are not. A simplistic form of train traffic governance is ''negative'' train control, where trains must stop when issued a stop order and can move in the absence of such. An example of negative train control is Indusi. In contrast, ''positive'' train control restricts the train movement to an explicit allowance; movement is halted upon invalidation. A train operating under PTC receives a ''movement authority'' containing information about its location and where it is allowed to safely travel. As of 2019, the U.S. freight rail industry trade organization AAR claimed that the nation's largest freight railroads were operating PTC across 83.2 percent of the required route miles.
